Answer 2

Problem Analysis

We are given that a lathe operator can produce 64 parts in 5 hours. We need to determine how many hours it will take for the operator to produce all the parts if they produce 32 parts per hour.

Solution

Let's calculate the number of parts produced per hour by the operator: - If the operator produces 64 parts in 5 hours, the rate of production is 64 parts / 5 hours = 12.8 parts per hour.

Now, we can use this rate to calculate the time it will take to produce all the parts at a rate of 32 parts per hour: - If the operator produces 12.8 parts per hour, it will take 1 hour to produce 12.8 parts. - Therefore, it will take 2 hours to produce all the parts at a rate of 32 parts per hour.

Answer

If the operator produces 32 parts per hour, it will take 2 hours to produce all the parts.
